However, multiple cells in a JT group should have the same user data to transmit simultaneously, resulting in a considerable backhaul burden. Even when cells are already equipped with caches in fifth-generation networks, JT groups, without effectively utilizing the caching data, still cause unnecessary backhaul data traffic. In this article, we investigate the JT grouping problem with the consideration of caches at cells. Then, we propose a genetic approach to solve the above problem with the objective of minimizing the amount of backhaul data traffic subject to the data-rate requirement of each user. The simulation results show that our proposed generic algorithm can significantly decrease the backhaul bandwidth consumption compared to the two baselines.<\/jats:p>","DOI":"10.3390\/s22197147","type":"journal-article","created":{"date-parts":[[2022,9,22]],"date-time":"2022-09-22T23:07:55Z","timestamp":1663888075000},"page":"7147","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Genetic Approach for Joint Transmission Grouping in Next-Generation Cellular Networks"],"prefix":"10.3390","volume":"22","author":[{"given":"Yu-Po","family":"Kuo","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering, National Sun Yat-sen University, Kaohsiung 804, Taiwan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1639-3403","authenticated-orcid":false,"given":"Ya-Ju","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, National University of Kaohsiung, Kaohsiung 811, Taiwan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7305-6492","authenticated-orcid":false,"given":"Tzung-Pei","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, National Sun Yat-sen University, Kaohsiung 804, Taiwan"},{"name":"Department of Computer Science and Information Engineering, National University of Kaohsiung, Kaohsiung 811, Taiwan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5958-8599","authenticated-orcid":false,"given":"Wei-Kuang","family":"Lai","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, National Sun Yat-sen University, Kaohsiung 804, Taiwan"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,21]]},"reference":[{"key":"ref_1","unstructured":"Cisco (2022, June 29).
